Effects Settings - Oberheim OB 12 Operating Manual

OB 12
From the EDIT EFFECT video page select field 2-EFFECTS SETTINGS; the display will show the
video page relating to setting of the parameters of the OVERDRIVE effect.
This algorithm allows the distortion required to be inserted in the effects chain. Conventional '60s-
style light distortions can be obtained, but the instrument can also produce powerful sounds typical
of contemporary rock music.
The video page is as follows:
containing the following programming parameters:
STATUS
([OVERDRIVE])
it (BYPASSED).
DRIVE: regulates the degree of distortion of the signal.
TYPE: sets the type of simulated amplifier brought to saturation.
HI-DAMP: regulates the cut-off frequency of a low-pass filter capable of eliminating all the
frequencies above that set, to allow control of the signal timbre.
LEVEL
([LEVEL] with the LED of the [LEVEL/PARAMETER] button off)
leaving the effect.
PARAMETER KNOB ASSIGNED TO: defines which of the parameters shown in the video
page can be regulated using the trimmer associated to the Overdrive effect (the first on the left
in the EFFECTS section of the front panel) when the LED of the [LEVEL/PARAMETER] key is
on.
Now use the [F2] button to select the CHORUS folder and thus display the page for programming
the effect. The Chorus is generated using two lines: one remains unchanged (signal received as
input) while the pitch of the other is slightly and cyclically by means of a modulant. The final sound
obtained is a little fuller, richer and "spacious" than the original.
The following effect parameters can be set:
STATUS
([CHORUS])
(BYPASSED).
RATE: regulates the modulation speed of the effect on the input signal.
DEPTH: regulates the modulation depth of the effect on the input signal.
: inserts the Overdrive effect in the effects chain (INSERTED) or bypasses
: inserts the Chorus effect in the effects chain (INSERTED) or bypasses it
: regulates the level of the signal
